Product details
Overview
BAS1602VH6327XTSA1 from Infineon Technologies is a silicon high-speed switching diode in SOT-23 package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, used in automotive signal routing and power rail clamping circuits per AEC-Q101 qualification.
For engineers reviewing the BAS1602VH6327XTSA1 datasheet, BAS1602VH6327XTSA1 pinout, BAS1602VH6327XTSA1 application, or BAS1602VH6327XTSA1 equivalent, this part supports fast transient suppression in 12 V automotive control modules, logic-level signal steering, and low-loss flyback snubbing where thermal resistance ≤120 K/W and junction temperature up to 150 °C are critical design constraints.
Technical Context
This diode operates as a unidirectional, single-anode–cathode switching element with low forward voltage (1.25 V at 150 mA) and minimal junction capacitance (2 pF at 0 V), enabling clean edge transitions in digital interface protection and DC-DC converter freewheeling paths.
Its AEC-Q101 qualification confirms robustness under automotive thermal cycling and humidity stress, while the SOT-23 footprint ensures compatibility with standard pick-and-place assembly and board-level reflow profiles targeting TS ≤ 120 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports operation across 12 V and 24 V automotive rails with margin against load-dump transients |
| Forward Current (IF) | 200 mA - sufficient for logic-level signal clamping and low-power switching in ECU I/O buffers |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation at >10 MHz switching frequencies in pulse-width modulated circuits |
| Junction Temperature (Tj) | 150 °C - allows sustained use in engine bay environments without derating below rated current |
| Thermal Resistance (RthJS) | ≤120 K/W - permits direct mounting on copper pours for passive cooling in space-constrained PCB layouts |
| Capacitance (CT) | 2 pF at 0 V - minimizes signal distortion in high-speed data line protection (e.g., LIN bus, CAN stubs) |
| Forward Voltage (VF) | 1.25 V at 150 mA - reduces conduction loss and self-heating during continuous clamping duty cycles |
Pinout & Package
Package: SOT-23 (SC-59), surface-mount, 3-terminal plastic package with gull-wing leads; standardized footprint per JEDEC TO-236AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Current entry point under forward bias | Connected to source-side of protected node (e.g., microcontroller output, sensor supply) |
| 2 (Cathode) | Current exit point under forward bias; reverse-biased terminal | Tied to reference rail (e.g., VCC, GND, or clamp voltage node) for unidirectional conduction |
| 3 (Cathode) | Second cathode terminal (dual-cathode configuration) | Enables common-cathode dual-diode layout in compact space; shares cathode connection for bidirectional clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including temperature cycling, HAST, and mechanical shock |
| Pb-free (RoHS compliant) | Meets EU Directive 2011/65/EU; compatible with lead-free reflow soldering profiles (peak 260 °C) |
| Low trr = 4 ns | Reduces switching losses and prevents shoot-through in synchronous rectifier and snubber applications |
| RthJS ≤ 120 K/W | Supports 200 mA continuous operation without external heatsinking when mounted on ≥1 cm² 1-oz copper |
| VRM = 85 V | Provides 5 V headroom above 80 V VR rating, accommodating transient overvoltage events in 24 V systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS12201LT1G | Same SOT-23 package; trr = 4 ns, VF = 1.25 V @ 150 mA, but VR = 70 V (10 V lower) | Not suitable for 24 V automotive systems requiring 80 V VR margin | Select only for 12 V-only applications with tighter board space constraints |
| Diodes Incorporated BAV99,215 | Dual-series SOT-23; trr = 4 ns, VR = 70 V, VF = 1.25 V @ 150 mA, but RthJS = 250 K/W (higher thermal resistance) | Limited to intermittent duty due to thermal derating above 75 °C ambient | Prefer for cost-sensitive consumer-grade designs where AEC-Q101 is not required |
Compared with NSS12201LT1G and BAV99,215, BAS1602VH6327XTSA1 delivers higher reverse voltage margin and superior thermal performance-critical for automotive under-hood deployment-while maintaining identical 4 ns switching speed and SOT-23 footprint compatibility.

FAQ
Is BAS1602VH6327XTSA1 pin-compatible with standard SOT-23 diodes like 1N4148?
No. While both use SOT-23 packaging, BAS1602VH6327XTSA1 has a dual-cathode configuration (pins 2 and 3 both cathodes), whereas 1N4148 is single-diode with anode–cathode–anode pinout. Direct substitution requires PCB layout revision to accommodate shared cathode routing.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature remains 150 °C regardless of pulse duration. Under pulsed conditions (tp < 1 ms), thermal resistance drops to ≤60 K/W, allowing peak forward current up to 400 mA for 10 µs pulses-provided average power stays within 250 mW and case temperature does not exceed 120 °C.
Does BAS1602VH6327XTSA1 support bidirectional ESD protection?
No. It is a unidirectional diode optimized for forward conduction and reverse blocking. For bidirectional ESD clamping, a dedicated TVS array (e.g., Infineon ESD204-B1-02EL) or back-to-back diode configuration is required-this part serves only as a single-quadrant switch or clamp.
Can BAS1602VH6327XTSA1 be used in place of BAS16W in existing designs?
Yes, with verification. Both share SOT-23 package and 80 V VR rating, but BAS1602VH6327XTSA1 has lower RthJS (≤120 vs. ≤125 K/W) and same 200 mA IF rating. Layout compatibility is confirmed; thermal performance improves slightly, making it a drop-in upgrade for new revisions targeting enhanced reliability.
